Homeostasis is important because the cells‚ blood and tissue fluids can change by slowing down or even stop a vital chemical reaction. Its aim is to keep the body to stay the same‚ at a normal condition. Negative feedback is when change is detected; there are steps when change is detected to get it back

    During a Muscle Contraction The muscle fiber is in a resting state. The resting state is slightly negative inside and slightly positive outside. It has to be in this state in order to receive a message. First the brain sends a message to the muscle using a neuron then reaches the axon terminal of the neuron. Calcium gates then open on the axon terminal allowing calcium to rush in. Ach release from axon terminals‚ diffuses across the synaptic clef and binds to (receptors) on motor end plate. Then

    1. INTRODUCTION There are many global connections between the three diaphragms. As stated by Andrew Taylor Still‚ “all parts of the body have direct and indirect connection with the diaphragm” (Frymann‚ 1968). These interrelationships amplify the importance of the synchronistic functions between the three diaphragms to facilitate a balance of the vascular‚ neurological‚ and physiological systems as a whole. Lesions and/or restrictions in the function of one of the three diaphragms will‚ directly

    Skeletal Muscle Lab Introduction: Motor neurons and muscle fibers are the building blocks of motor units and where they intersect is called the neuromuscular junciton. The region where the flattened end of a motor neuron transmits neural impulses to a muscle is the motor end-plate. The end plate potentials depolarizes skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. The process of contraction of the muscle cell is called excitation-contraction
